Thank you very very much. Now everything is like it should be. And I added a menu for the game as well. It's my luck that we had not to present it in school today so I could complete it right now but only with your help. You safed my life. Thanks :)

Anytime you ask a question and the word 'when' is involved, you are really saying 'if ever'. The ever part is dealt with just by using the 'act' method, which is repeatedly being run throughout the execution of your project as long as the actor is in the world (the actor would need to be in the world to reach those coordinates anyway). So, your statement is this: if location of actor is (0, 2), remove it from the world; Do you know how to get the location of the actor? Do you know how to have the actor remove itself from the world which it is in? Can you now take the statement and

Yea i used this code to fix it: <Code Omitted>

I think you want line 12 placed after line 20; otherwise, your enemy will move for all actors in the direction currently facing and then turn toward the closest one at the end. Also, with the move inside the loop, like that, the distances will be changing while you are trying to figure out the closest one, which may give false results.

Oh you're right. Knew it would be something stupid! Cheers.

Never mind, I have fixed it

You are missing the following: * a semi-colon, ';', at the end of line 36 of the Emoticon class; * a constructor declaration statement between the field declarations on lines 18 and 19 and the constructor code, lines 36 through 39 of the Emoticon class; * a dot, '.', before the file name suffix on line 55 of the Emoticon class; Then, lines 37 and 38 are trying to set arrays to String values. I think you want to save individual Strings in each of the Emoticon objects created, not arrays of Strings. Lint 48 of the HomeworkWorld class is not needed. That condition is accounted for in t

I first looked at your HealthBar class. You do not need to update its image every act cycle. After the initial creation of the HealthBar object, when you call 'update' to set the initial image of the bar, the only time you need to update the image is when the value of the bar changes (in the 'loseHealth' method after the value is changed). Add the 'update' call there and remove the act method from the class. Then, in your Tojan class, I notice that line 252 is trying to call the 'loseHealth' method on the class, 'HealthBar', and not on an object of the class, 'healthBar' (declared on lin

No, none of this is working. but, I did get it to work by changing the greenfoot source code. Thanks anyway.

Where is the code where he actually dies?

From your Main world: <Code Omitted>From an Actor class: <Code Omitted>As an alternative, you could make the 'music' field a 'static' field and use the following from anywhere: <Code Omitted>

You also might want to make moveDelay a private int.

'static' fields that are assigned their values when declared are set during compilation; when a tank is created is of no consequence.
